Description
Technical Field
The utility model relates to a heat recovery need not condensing gas heating device in air heating equipment field.
Background
Need heating the air supply in some production technologies, hot air drying system generally utilizes the combustor to heat the air, at present, common gas heating system comprises air inlet pipe way, heater strip, thermal-insulated cotton, play gas line and condenser, and the air is by air inlet pipe way through heater strip heating part, and the air is heated and has carried a large amount of heat energy, and its temperature of compressed air who contains a large amount of heat energy can reach more than 200 ℃ usually, gets into the condenser through going out the gas line and cools off, discharges the heat constantly in the equipment internal environment. The common heating system is a high-power electric device, the power of several kilowatts of the common heating system is completely converted into heat energy, and the air heating is only used as catalysis and almost consumes no energy, so that a large amount of energy is continuously discharged, and the waste is very serious.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a heat energy recovery device without condensing gas.
The utility model discloses a realize through following technical scheme:
the utility model provides a heat recovery need not condensing gas heating device, includes heating pipe and heating furnace, and in the heating furnace was arranged in to the one end of heating pipe, its characterized in that: the heating pipe is a single-path double-layer pipe and consists of an air outlet pipeline and an air inlet pipeline, the air outlet pipeline is positioned in the air inlet pipeline, the end part of the heating pipe in the heating furnace is of a closed structure, the end parts of the air outlet pipeline and the air inlet pipeline in the heating furnace are opened and communicated, a heat source in the heating furnace heats gas in the air inlet pipeline, and the heated gas is led out by the air outlet pipeline; the technical scheme is further explained as follows: the air outlet pipeline and the air inlet pipeline are in a closed circulation structure at the outer pipeline; the technical scheme is further explained as follows: an overheat protector is arranged on the heating pipe; the technical scheme is further explained as follows: the air outlet pipeline is made of high-thermal-conductivity red copper.
The utility model discloses following beneficial effect has:
firstly, reducing heat energy consumption and improving the utilization efficiency of heat energy: the heat is recovered by back flushing of inlet air and outlet air, the constant temperature of the heating furnace is more durable, and the average power is reduced by 2/3;
secondly, the air supply amount is not affected: because the flow rates of the inlet air and the outlet air are equal, the brought heat is more, and the heat recovered by back flushing is increased proportionally;
thirdly, reducing the volume of the equipment: because the external gas loop is omitted in the heating furnace, the volume of the heating furnace can be reduced, and because an external condenser is not needed, the volume of equipment can be greatly reduced;
fourthly, the application range is wide: the device can be used in cooling or heating equipment of gas.

FIG. 2 is a view showing the structure of a heating pipe.
Fig. 3 shows a heating tube end structure.
In the figure: the heating furnace comprises a heating furnace 1, a heating pipe 2, an overheat protector 3, an air inlet pipeline 4 and an air outlet pipeline 5.
Detailed Description
The following description of the present invention is provided with reference to the accompanying drawings:
as shown in the figure, the structure of the heat energy recovery non-condensing gas heating device comprises a heating furnace 1, a heating pipe 2, an overheat protector 3, an air inlet pipeline 4 and an air outlet pipeline 5. The invention relates to a heat energy recovery and condensation-free gas heating system for supplying gas to a zero-level air generator, wherein a gas heating device is arranged in a pipeline, a gas circuit of a whole heating furnace adopts a built-in loop, one end of a heating pipe is arranged in the heating furnace, the heating pipe adopts a single-path double-layer pipe, and a gas outlet pipeline is arranged in a gas inlet pipeline; in the interior of the heating furnace, an external pipeline at the terminal of the heating pipe is of a closed structure, the end parts of the gas outlet pipeline and the gas inlet pipeline in the heating furnace are open and communicated, an internal pipeline is slightly short and open, and high-temperature compressed gas returns from the direction indicated by an arrow.
The heat energy recovery does not need the characteristics of condensing gas heating device structure as follows:
1. the heating furnace is used for carrying out back flushing and cooling on high-temperature air discharged from the heating furnace by using the air inlet of the heating furnace, and bringing heat back to the heating chamber.
2. The air outlet pipeline is made of red copper with excellent heat conductivity, and the heat dissipation performance of the compressed air is very good, so that most of heat brought out by air outlet can be dissipated into the air inlet pipeline and then is brought back into the heating chamber by air inlet.
The above description is only some embodiments of the present invention, and for those skilled in the art, a plurality of modifications and improvements can be made without departing from the inventive concept, and these modifications and improvements all belong to the protection scope of the present invention.
